Paca is a wild rodent typical of the tropical region. In order to study this species with focus on the proper management and preservation, this study aims to characterize the histochemistry of the accessory glands of the reproductive tract of the male paca. For this purpose, histological sections were stained with Periodic Acid-Schiff (PAS), Alcian Blue (AB), PAS + AB e PAS + Amilase. In the histochemical reaction of the bulbouretral gland was found that the epithelium produces secretion rich in neutral and acid glycoproteins, glycosaminoglycans, and in some regions produces more than one type of secretion. The epithelium did not contain any glycogen. In the vesicular gland the epithelium had bush border stained by neutral glycoproteins, but no acid glycoproteins, glycogen or glycosaminoglycan. The coagulating gland showed small amount of neutral glycoproteins in the brush border of the epithelium, without glycogen. It is concludes that the accessory glands of paca have histochemical characteristics that share some similarity with other species of the Order Rodentia, with some glands with neutral and acid glycoproteins, mainly in the epithelium of the bulbouretral gland and in the brush border of the other glands. |
